摘　　要：明确优秀速滑选手间技术上的细小差异和影响运动成绩的决定因素不仅对改进技术,而且对运动训练具有重要的意义。运用运动生物力学方法,比较了优秀组与一般组滑跑同一距离项目中蹬冰技术之间的异同性。结果表明:输出功率总量参数决定水平相近的运动员之间成绩上的微小差异;优秀组通过高步频、短步幅的方法实现输出功率总量的提高;提出动点支撑的频幅特点有别于定点支撑的观点。It is essential to make it definite the tiny technical differences and determinant influences of sports score amnng outstanding speed skating contestants, which contributes a lot to the changes of techniques and plays very important role in the sport training. Adopting the Biomechanics mehods, this study conducted a comparative analysis on the similarities and differences in the techniques of pedaling the ice between the outstanding group and in common group, The results of this study indicated that the total quantity parameter determined the small differences in the scores among the athletes with the similar scores; the advanced group achieved the increase of total quantity parameter output through the high pace, short stride width method; it is proposed that a moving point strut frequency characteristic is different with the fixed-point strut the viewpoint.
